ATTACHMENT FOR HOT-All REGISTERS.

Specification of Letters Patent.

Patented Aprii 2e', 1907.

' Application led February 12, 1901. Serial No. 47,045.

for Hot-Air Registers; and we do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an attachment for hot air registers.

The object of the present invention is to provide an attachment for the register by which the cold air in the room is prevented from entering the register flue and the hot air escaping therefrom is caused -to be deflected downward toward the iioor.

A further object is to provide the attachment with a device for separating the dust, soot or other impediments from the hot air as it escapes from the register and to provide g means by which the slats may be operated fire m the exterior of the attachment.

The invention embodies a rectangular cas- 'ing adapted to be fitted to the register and project from the face plate thereof into Athe room, the top of said casing being bent downward to deflect the heat toward the floor, a

screen pivoted in the casing and adapted to be turned up under the delector or down beneath the same and an operating rod for the slats extending through the side of the casing.

The invention is illustrated in the accompanying drawings in which 1'- Figure l is a perspective view of our improved register as it appears in use. Fig 2 is fx. vertical section of the same. Fig. 3 is a transverse section on the line icof Fig. 2 looking in the direction of the arrow.

Referring to the drawings 1 designates the wall of the building against which the face plate A of the register is placed. In the wall is an opening in which is fitted a casing a containing the pivotal slats a.

Ourilnprovement consists of a sheet metal casing'B having its inner edges bent inwardlv "as at l) to be clamped between the face plate "and the wall of the building. envelopes the sides and ends of the face plate This casing B A and extends outwardly therefrom into the room, its outer longitudinal side edges being l l inclined so that its base is of less depth than its top. The top ofthe casing is curved outwardly and downwardly to form a deiiector b by means of which the heat is given a downward course as it escapes from thc register.

Mounted in the deiiector b is a screen C braced and held together by the rods ci spaced apart along these curved edges of the end plates. The curved edges of the segments coincide with the curved inner face of the deflector. On thecurved edges of the plates is secured a piece of reticulated material d which catches or arrests dust, soot, or other foreign matter which might escape through the register.

The screen stands normally, and automatically, across the casing with its outer edge portion lapped over the lower edge portion of the delector and its inner edge lodged against the face-plate of the register, as indicated in descending debris as may accompany the discharging currcnt.

The plates c and c are secured to a rod e having an eye c formed on one end to provide a handle and this rod is pivoted in lhe sides of the casing beneath the deflector so that when it is rotated by the handle e/ which projects beyond the side of the casing the screen will be turned up in the deiiector or beneath the same as shown in Figs. 1 and 2. When turned up the deiiector may be readily cleaned.

Tov conveniently operate the slats without lifting the screen, we provide an operating rod F having a handle f at one end projecting through one side ofthe casing and secured at its other end to a stud g of a sliding plate G. This sliding plate G is confined within the casing and engages the ends of thepivotal slaU a andits stud g extends through a slot in the face plate A so that when the operatinU rod F is pulled `the plate will also be vpuilled to close the slats.

As the tendency of hot air is to rise to the highest point possible, the air ascending the flue will naturally seek the highest point thereof, and the'greater part in escaping into the room will pass through the upper portion of the face plate7 strike the deflector b/, and pass downward through tlm screen, which acts to free it from soot ard dust.

having the segmental end plates c and cA Fig. 2 ofthe drawings, so as to intercept such IOO l/Vith this particular casing the velocity of the hot air is greater than with the usual registers, because it is'well known that ordinarily the cold air in a room enters the bottom of the register, takes a downward course, and checks the ascent of hot air shutting olf 40% of heat, While in the present invention the bottom and sides of the casing serve as a guard to prevent this; consequently the hot air strikes against the deflector with considerable force and is then defie'cted toward the floor distributing the heat throughout the room.

Having thus described our invention, we claim:

The combination with a hot-air Wall regis- Y ter of an attachment comprising a casing havin@ its inner edges bent inwardly to engage beiind the flanges of the face-plate of the register and the body of the casmg standing out from the wall and curved downwardly at its upper portion to form a deflector the upper portion Vof the casing being bulged as coincident with the curved contour of the delector, and a metal screen having its ends secured to the curved edges of the segments, said screen standing normally across the casing under the deflector, substantially as shown.

In testimony whereof we aflix our signatures, in presence of two witnesses.
